If remote voltage adjust is not used, short terminals 6 and 7 together.
Short terminals 50 and COM together for 50 Hz operation. Leave unconnected for
60 Hz operation.
5 The secondary winding of a sensing transformer must be grounded as closely to
the transformer as practical. When interconnecting more than one transformer,
ensure that the secondary winding of only one transformer is grounded.

WINDING
5 The secondary winding of a sensing transformer must be grounded as closely to the
transformer as practical. When interconnecting more than one transformer, ensure
that the secondary winding of only one transformer is grounded.

NOTES
1. When more than three generators are to be paralleled,
continue connections as shown.
2. Paralleling CT polarities are shown with ABC phase rotation.
When connected in cross-current, external resistors may be
required to improve reactive load sharing among generators using
regulators with dissimilar current input burdens. Use the following
table as a guide.
The secondary winding of a sensing transformer must be
grounded as closely to the transformer as practical. When
interconnecting more than one transformer, ensure that the
secondary winding of only one transformer is grounded.
